Dole Japan is selling limited edition bananas in Tokyo known as Gokusen bananas.
As far as exotic and luxurious fruits go, the banana is one that doesn't rank very high on the list. What makes these bananas worthy of their high price and fancy packaging is its reputation for being "Dole Japan's most delicious and fragrant banana." The Gokusen bananas are grown in the Philippines at 500 meters above sea level and weigh 200 grams (which is 100 grams more than you're typical banana).
Priced at 590 Yen ($5.80) each, the Gokusen bananas come packaged in a beautiful box, and even have serial numbers. While the Gokusen bananas have been sold since 2009, the marketing stunt was designed to coincide with the date of May 9 (5/9) in order to create a pun of sorts as the word Goku when broken up translates to "go" meaning 5 and "ku" meaning 9.
